Mark Cuban's wife has always been at the center of attention when the wealth of the successful American businessman/investor is being talked about. For one thing, Forbes has silently implied in 2000 that Cuban's then-girlfriend and now his better half was a gold-digger for his fortune. But who is Mark Cuban's wife really?

According to Playerwives, Cuban's marital partner is Tiffany Stewart, the mother of his two kids: Alexis Sofia and Alyssa. The two reportedly got married on September 2002.

Forbes says Mark Cuban met Tiffany at the gym in 1997, and the two had been dating since until they decided to tie the knot after five years of being together.

Mark Cuban's wife, Tiffany Stewart, is an advertising executive, according to BornRich.com, but it isn't clear whether she is still working or if she has decided to become a full-time mom to their children.

Cuban's family is said to reside in a lavish mansion in Preston Hollow area of Dallas, which is believed to be worth $15 million.

Mark Cuban is the owner of the National Basketball Association's Dallas Mavericks. He also owns Landmark Theatres and Magnolia Pictures. Furthermore, Cuban is the chairman of the HDTV cable network AXS TV.

For many years now, Cuban has remained on the upper half of the Forbes 400 richest list because of his behemoth fortune amounting to $2.5 billion.
